#1282 fixed sertting a large number of macro characters doen't scale well Gary Byers
Description

People have reported that it can be prohibitively slow to call SET-MACRO-CHARACTER on all potential Unicode characters.

I'm not surprised by this, but I'm not sure that there's a good reason to make it impractical for someone who wants to do this to do so, either.

changing the data structures that CCL uses to associate characters with functions can affect things like SET-SYNTAX-FROM-CHAR and COPY-READTABLE as well as SET-MACRO-CHARACTER and (poossibly) SET-DISPATCH-MACRO-CHARACTER.

#1340 fixed apparent bug in UPGRADED-ARRAY-ELEMENT-TYPE Gary Byers
Description

in the current trunk CCL (and likely earlier) pm x8664

? (upgraded-array-element-type '(signed-byte 60))
FIXNUM

ok. but

? (upgraded-array-element-type '(unsigned-byte 59))
(UNSIGNED-BYTE 64)

does not seem to be ok

I think that the problem is likely in the order in which CASE clauses are tested by CCL::CTYPE-SUBTYPE

#1351 fixed arm kernel does not need to be linked specially Gary Byers
Description
